黑山湖特大桥跨兰新铁路零号块临时固结计算

Computation on Temporary Consolidation of Zero Number Block of Heishanhu Large Span Crossing LanXin Railway

连续梁桥墩和梁存在支座,是铰接关系。而连续梁桥采用悬臂施工在没有合拢前是悬臂状态,为了保证挂篮施工过程的安全性,必须对连续梁桥墩和梁进行临时固结处理。因此临时固结成败直接关系着连续梁悬臂施工的安全和稳定。本文结合黑山湖跨兰新铁路立交特大桥,分析连续梁桥临时固结的设计计算。

There are supports between the continuous beam bridge piers and beams, which are articulated together.In order to ensure the security of the hanging basket construction process, it is necessary to solidify continuous beam bridge piers and beams. So temporary consolidation directly determines the success or failure of the continuous beam cantilever construction.Taking the overpass crossing Lanxin Railway in Heishanhu as a case study, this paper analyzes the computation of the bridges＇ temporary consolidation.
